Abstract | Recently, we reported the successful coupling of a high-pressure diamond-anvil cell (DAC) to a micro-Raman spectrometer and demonstrated the simplicity of this spectroscopic approach in examining the properties of some inorganic materials at external pressures approaching 70 kbar (~70 000 atm). One of our current interests involves the study of the phase-transition behavior of orientationally disordered solids or “plastic crystals.” As they are sometime termed. These materials are new attracting considerable industrial attention because of their potential uses in passive, thermal-energy storage devices for buildings and even clothing. I the present work, we have used the DAC-micro-Raman technique to investigate several compounds with cage structures, e.g., o-carborane, B₁₀C₂H₁₂ (I, where the H atoms have been omitted for the sake of clarity) and the geometrical isomers 1- and 2-chloroadamantane C₁₀H₁₅Cl (II and III). These :globular” molecules are known to exhibit order-disorder phase transitions in the solid state at low temperatures, and we anticipated that it might also be possible to induce the same phase transitions by application of high external pressures. |
